Rubber tubing is a versatile and essential tubular product primarily crafted from high-quality rubber, typically comprising an inner and outer rubber layer intertwined with a robust skeleton layer. It's ingeniously designed to transport a wide range of mediums such as gases, liquids, slurries, or even granular materials. The core essence of rubber tubing lies in its ability to seamlessly facilitate the transmission of diverse media through its exceptional elastic sealing and pressure-bearing capabilities. This remarkable product finds widespread utility across various domains including industry, automotive, and medical treatment, making it an indispensable asset in these fields.
1. Introduction of Rubber Pipe Material
Crude Rubber: Known for its exceptional high elasticity, wear resistance, and remarkable bending and scratching characteristics, it is ideally suited for low-pressure environments, providing reliable performance.
Protobutadiene Rubber (SBR): Renowned for its excellent wear resistance and cost-effectiveness, though it exhibits poor oil resistance, making it a great choice for specific applications.
Cis-Polybutadiene (BR): Offers superior moisture resistance along with outstanding low temperature tolerance, retaining its elasticity even at a chilling -50ºC, thereby ensuring dependable performance.
Nitrile Rubber (NBR): Boasts exceptional oil resistance, particularly effective against mineral and lubricating oils, though it lacks in ozone and high temperature resistance.
Chloroprene Rubber (CR): An all-rounder with a balanced performance, providing oil resistance, ozone resistance, and aging resistance, making it highly versatile.
EPDM Rubber (EPDM): Offers remarkable high temperature resistance ranging from -50 to 150ºC, coupled with strong weather resistance, perfect for long-term outdoor exposure.
Fluorine Rubber (FKM): Capable of withstanding extreme temperatures from -20 to 250ºC, and highly resistant to chemical corrosion, making it suitable for the harshest environments.
Silastic (VMQ): Excels in high temperature resistance from -70 to 300ºC, with high transparency and excellent electrical performance, perfect for demanding applications.
Chlorinated Sulfated Polyethylene Rubber (CSM): Offers resistance against strong acids and alkalis like concentrated sulfuric and nitric acids, with strong permeability resistance.
Conductive Rubber: Features built-in conductive fibers or metal mesh to prevent static accumulation, ensuring safety and reliability in sensitive applications.
Fire Retardant Rubber: Enhanced with flame retardants like aluminum hydroxide, this product has successfully passed the stringent UL 94 flame retardant certification.
2. Structural Composition of the Rubber Pipe
The Glue Layer: This critical layer comes into direct contact with the conveying medium and is engineered for superior wear and corrosion resistance, including oil, acid, and alkali resistance, ensuring long-lasting durability.
| casing pyl |
Enhance the strength of the tube body, including cotton thread, steel wire, synthetic fiber, etc., to determine the pressure bearing capacity (e. g., the steel wire woven layer can withstand 80~600MPa pressure). |
| External glue layer |
Protect the internal structure from the external environment (such as ultraviolet light, mechanical friction). |
3. Structurally, rubber pipes are categorized into various types, including sandwich hoses, braided hoses, winding hoses, and full hoses.
4. Working Principle of Rubber Pipe
| Pressure transmission and energy buffer |
The hydraulic hose transfers the force through the fluid pressure, and uses the elastic shape of the rubber to absorb the pressure pulsation, and reduce the vibration of the system. For example, the hydraulic pipe of construction machinery bears high pressure (up to 60MPa or above) through a multi-layer steel wire reinforced layer. |
| Shock absorption and displacement compensation |
Rubber soft connection (e. g., flexible rubber joint) absorbs pipe displacement through the elastic deformation of the curtain layer and wire ring to reduce operating noise, which is suitable for pump valve connection and frequent vibration line. |
| Media isolation and leakage prevention |
The compactness of the inner adhesive layer combines with the protection of the outer adhesive layer to prevent the leakage of water, gas or chemicals. For example, the mobility of the coolant between the car radiator and the engine. |
5. Application Areas:
| industrial circle |
Welding gas delivery, hydraulic system, mine ventilation. |
| automotive filed |
Coolant circulation, fuel transmission, air-conditioning system. |
| Medical field |
Infusion tube, surgical instrument catheter. |
| The field of agriculture |
Irrigation system, aquaculture equipment. |
| New energy field |

6. Standardization and Security Guarantee:
| high-voltage insulation test |
Burst pressure is 3 times the working pressure (such as hydraulic hose). |
| degradation testing |
Simulated high temperature / UV environment assessment life (theoretical value of more than 15 years). |
| Environmental requirements |
Biological based rubber and low VOC (volatile organic compounds) formula meet the sustainable development needs. |
